"Accidentally" discovered on June 16, 1948, it is an area approximately 50 feet in diameter in which the laws of gravity seem to be repealed.  There is a cabin on this site that "accidentally" slid down the hillside, and this is where visitors can experience this wonder.

Supposedly a geologist from the University of Wisconsin determined that the high concentration of igneous rock on the other side of the hill was the cause of the gravitational anomalies.

A concentration of igneous rock would not cause gravitational anomalies.

From the construction it is obvious that the cabin was deliberately built on a slant on a steep hill.

• Water flows uphill
• Balls roll up an incline
• Pendulums hang crookedly
• Chairs balance on only two legs
• People are unable to stand erect or to walk straight

The cabin was intentionally constructed as a Wisconsin Dells tourist attraction, and the effects can be easily explained as optical illusions produced by the tilted design of the structure.  Although it's a fun place to visit and experience, there is nothing paranormal or unexplained here.
